You can put this solution on YOUR website!
Let r=rare of speed, t=time in hrs, d=dist in kph.
\n" ); document.write( "rt=d
\n" ); document.write( "t=d/r
\n" ); document.write( "d/78 + 1/3 = d/72
\n" ); document.write( "936d/78 + 936/3 = 936d/72
\n" ); document.write( "12d+312=13d
\n" ); document.write( "d=312 km.
\n" ); document.write( ".
